espanolEn este estudio hemos querido trazar un primer acercamiento al estudio de la lengua poetica del autor italiano Tommaso Stigliani y lo hemos hecho analizando su mayor obra, Il Mondo Nuovo (1628), poema epico sobre el descubrimiento de America. Hemos analizado los principales fenomenos de la ortografia, la fonetica, la morfologia, la sintaxis y el lexico que aparecen en el texto, teniendo en cuenta la norma linguistica del siglo XVII y las opiniones y teorias de los principales linguistas de la epoca. Con este estudio, por tanto, ofrecemos un acercamiento a la concepcion de lengua poetica que Tommaso Stigliani, a traves de su poema y de sus escritos teoricos, puso de manifiesto a lo largo de su carrera literaria. EnglishIn this study, we have attempted to make inroads into the study of the poetic language of the Italian author, Tommaso Stigliani, analysing his principal work, Il Mondo Nuovo (1628), an epic poem on the discovery of America. We have examined the main phenomena of orthography, phonetics, morphology, syntax and lexicon that appear in the text, taking into account the linguistic norms of the 17th century, as well as the opinions and theories of the major linguistic experts of that period. Our study, therefore, gives an insight into Tommaso Stigliani?s conception of poetic language, which, through his poem and his theoretical writings, he maintained for the duration of his literary career
